JOHN C. TUTTLE, OF RON, OHIO, ASSIGNOR TO THE FIBESTONE TIRE AND RUBBER OOMPANY, OF

RON, OHIO, A CORPORATION OF OHIO.

some it Application filed December 21; 1920. Serial No. 432,287.

To all whom it may concern:

Be it known that I, JOHN C. TU'r'rLn, a citizen of the United States, residin at Akron, in the county of Summit and tate of Ohio, have invented certain new and useful llm rovements in Solid Tires, of which the 0 owing is a specification.

Thisinvention relates to improvements in resilient tires, particularly solid-rubber tires, such as used on trucks or commercial vehicles, and is designed to provide an efficient and efi'ective gripping surface, which will efiectually cling to the surface of the 1 road or pavement and prevent skidding and tire tread which will gri increase traction. It is the purpose of this invention to improve upon certain features of construction and eliminate objectionable designed for this purpose. One of the principa objects of this invention is to afford a the road surface, properly so that of a suction tire but which will vent itse f noise incident to. the use will be eliminated. I

- These and other advantages arise from a tire of the design herein illustrated, and

while the showing and description are def.

tailed, it is not to be understood that the nvention is limited to such details, as

changes may be made without departing from the principle of the invention and without sacrificing any of its benefits.

In the drawing:

Fig. 1 is a lan view looking down upon the tread oft e tire.

. Fig. 2 is a longitudinal section on the hue 2-2 of Fig. 1.

Fig. 3 is a transverse-section on the line 3-3 of Fig. 1.

Fig. 4 is a Fig. 1. The tire is carried u on a rim 1 of any desired design and to t e outer surface of the rim is secured, preferably by vulcanization the solid tlre designated by the numeral 2. 1

In the tread surface of the tire is arranged section on the line 44 of a plurality. of suction cups or sockets 3,

which are arranged about the tread of the preferably in parallel rows the cups in different rows being arranged in staggered relation. These'suction cups extend into the tire and are shown as pyramidical in shape, 'taperin inwardly toward the center of the tire. e shape and degree of. taper may be luralit varied without afi'ecting the principles of the invention, it being the purpose to make the cups ofsuch depth that sufiicient suction will be obtained in rollingfover the road surface to prevent sli ping. or skidding. The staggered position o the cups insures that there will always be one or more cups in contact with the road.

Tread surfaces are old in the art, but the noise occasioned by the running of the tire over a smooth pavement, due to the release of the vacuum at each cup,.has is the object of this invention to eliminate the noise without materially affecting the suction. q

For this purpose any suitable number of cups are connected by longitudinal grooves or passageways 4 which are approximately half the depth of the cups. It is preferred that the grooves be arranged as shown in the drawing, that is connecting every three cups, and with the grooves in staggered relation. B this arrangement the several cups are re eased from contact with the road proven objectionable and it provided with suction cdps and are ventedg at the proper time so that v made within the scope of the invention without avoiding the essential features thereof.

I claim:

1. In a resilient tire construction, a

of suction cups arranged circumerentia 1y of the tire, and a circumferential groove in the tread of the tire communicating with portion of he area of each cup and adapted to relieve the vacuum therein.-

2. In a resilient tire construction, aseries of suction cups arranged in parallel rows about the tread of said tire, and grooves extending circumfere'ntially-of said tire and,

connecting groups of said cups, the grooves in difierent rows bemg arranged in staggered relation.

3. In a resilient tire construction, a series rtain of the cups throughout a" ets are shown, the invention lation of suction cups arranged in parallel rows about the tread of said tire, the cups of different rows being arranged in staggered reand short grooves connecting a plurality of cups circumferentially of the tire, these grooves being of less depth than the cups.

4. In a resilient tire construction, a series of suction cups arranged in parallel rows about the tread of said tire, the cups of different rows being arranged in staggered relation, and short grooves connecting a plurality of cups circumferentially of the tire, these grooves being of less depth than the cups and arranged so as to break joint transversely of the tire.

5. In a resilient tire construction, a plurality of suction cups, arranged in rows about the tire, and grooves connecting certain of said cups, said grooves being of less depth than the cups and arranged at the sides of the cups.

6. In a resilient tire construction, a plurality of suction cups extending Wardly from the tread of the tire and a groove arranged circumferentially of the tire and connecting certain of said cups, said groove being of less Width and depth than the cups.

7. In a resilient tire construction, a plurality of suction cups extending inwardly from the tread of the tire, and a groove arranged circumferentially of the tire, connecting certain of said cups, said groove being of less depth than the cups, and communicating With said cups at the sides thereof. 1
